Severe sensitivity to Contrast Increase

Summary

A Contrast Increase test was performed on resnet-50, in which a 13% failure rate was observed. In at least one case, the model's prediction changed 0.57. This caused the label to change from dugong, Dugong dugon to grey whale, gray whale, devilfish, Eschrichtius gibbosus, Eschrichtius robustus.

Test Information

This test measures the robustness of the model to Contrast Increase transformations. It does this by taking a sample input, increase image contrast, and measuring the behavior of the model on the transformed input.

Why is this important?

Production inputs can have unusual variations amongst many different dimensions, ranging from lighting changes to sensor errors to compression artifacts. It is important that the models are robust to the introduction of such variations.
